The picture on the front cover of 0' Shaughnessy Dam
was taken on June 7, 1923, before the dam was raised
an additional 85.5 feet.
In the 75th year since the first lands were acquired for the
Hetch Hetchy Water and Power system, and in the midst of a very
dry year, it is fitting to recognize the foresight, industry
and dedication of the people who conceived, built and operate
that system. One and three-quarter million San Francisco Bay
Area residents receive a supply of first quality water from
Iletch Hetchy. How did it all come about?
The Metropolitan Bay Area of 1901 consisted of a San Francisco
of 350,000 population, and a collection of small, quiet towns
around the Bay. Booming growth, a high level of civic pride,
and t he belief of every citizen that San Francisco was to be
the leading metropolis of the Pacific Coast were the keynotes
of the times.
Some dissatisfaction with the commercial supplier, the Spring
Valley Water Company, prevailed, occasioned by high rates,
periodic shortages and recurring water quality problems. That
dissatisfaction had prompted language in the Charter enacted
in 1900, setting as a goal the acquisition and construction of
a municipally owned water supply system. What was needed was
a plentiful, high-quality water source that would meet the
area's need for at least 100 years. Looking east to the Sierra
Nevada, the planners found such a source in Yosemite National
Park. But the water was 150 miles awayl
The "City that knows how" was determined that the water system
would be built, and the first land was purchased, and water
rights established, in 1901. The ensuing struggle for permis-
sion to build a dam in Hetch Hetchy valley went on for years.
When the United States Congress confirmed the City's right to
proceed in 1913, construction commenced on the largest such
project on the Pacific Coast up to that time. After 21 years,
and the expenditure of some $100 million, the first water
arrived at Crystal Springs Reservoir via the Hetch Hetchy
aqueduct in 1934. The drama surrounding the leadership, poli-
tics, and the engineering and construction effort involved in
the project would be worthy of an epic novel, as expansion of
the system to meet water and power demand continues down to the
present .
The large and complex system was designed to be built in incre-
ments as demand increased. The master plan concept of a full
gravity aqueduct system to Crystal Springs, established in 1912,
has been followed as the system has grown through the years to
the present capacity of 300 million gallons daily. As a by-
product of the falling water, hydroelectric generating capa-
bility of 340 megawatts has been constructed; a major economic
asset for San Francisco. Additional elements of the system are
planned for construction as the demand increases.

Today, the benefits of the Hetch Hetchy project are so matter-
of-factly accepted that the public has granted the system its
highest accolade: cheap, pure and plentiful water is taken for
grant cd !

:.
The last concrete in the original O'Shaughnessy Dam
construction was poured in April, 1923, bringing the
total to 398,000 cubic yards. The height of the dam
was 226.5 feet above the original streambed and 344.5
feet from the bottom of the foundation. It was 298
feet thick at the base and 15 feet at the top. At the
time it was constructed, it was the second highest dam
in the United States, Arrowrock in Idaho winning by
ten feet. Between 1934 and 1938 it was raised an
additional 85.5 feet.
HIGHLIGHTS
Financially, the outcome of Hctch Hetchy's Water and Power
system operation for 1975-76 was influenced by two major events
which occurred during the year - one man-made and the other
the result of a natural occurrence.
Breakdown of wage negotiations for the upcoming fiscal year
between City's crafts workers and the Board of Supervisors
resulted in a 38-day strike by City employees including electri-
cians, plumbers, carpenters, laborers, street cleaners, etc.
who are members of the crafts union. The strike began March
31, 1 (.l 7 6 and ended on May 8, 1976. The public transit system
was quickly brought to a halt when the Municipal Railway drivers
joined the strike at the very outset. The importance of the
Hetch Hetchy Water and Power system operation to the success or
failure of the strike was not to be overlooked. It, too, was
forced to shut down with all hydroelectric generators stopping
production at 1400 hours on April 2, followed by complete
cessation of water delivery to the San Francisco Water Depart-
ment for domestic purposes.
The drought brought on by the lack of precipitation in the
winter of 1975-76, resulting in the smallest snow melt runoff
from the Hetch Hetchy, Cherry and Eleanor Watersheds in the 59
years of record, has left the three reservoirs at less than
601 full at the end of the report year. In order to conserve
as much water as possible for domestic use in the Bay Area, the
average daily power draft at Kirkwood and Moccasin Powerhouses
beginning June 1, 1976, was reduced to 300 million gallons per
day to coincide with the Hetch Hetchy Aqueduct capacity and the
anticipated San Francisco Water Department demand for the next
several months. In addition, the power draft at Holm Powerhouse
was reduced to 200 cubic feet per second in order to conserve
water at Lake Lloyd so that, if later conditions require, such
water can be directed into the Hetch Hetchy Aqueduct.
Ill Till HETCHY ORGANIZATION AND FUNCTIONS
Under policies established by the San Francisco Public Utilities
Commission, the HETCII HETCHY WATER AND POWER DEPARTMENT and the
BUREAU OF LI CUT, HEAT AND POWER serve the City and County of
San Francisco in the dual function of operating department and
service bureau.
Iletch Iletchy is a municipally-owned system of storage reservoirs
and aqueducts which collects water from the Tuolumne River
watershed and delivers it to the San Francisco Water Department.
As a by-product of falling water, Hetch Hetchy operates and
maintains hydroelectric generating stations and high voltage
transmission lines for the production and distribution of elec-
tric energy.
Through its Transit Power Division, Hetch Hetchy has funded,
operated, maintained and provided improvements for the electric
facilities of the San Francisco Municipal Railway since July 1,
1969.
In order to handle this additional responsibility, Hetch Hetchy
assumed control of the equipment and personnel of the Overhead
Lines and Motive Power Sections of the Municipal Railway.
All of Hetch Hetchy' s expenses, including those of the Transit
Power Division, are supported by water and power revenues.
The Bureau of Light, Heat and Power administers contracts for
furnishing electric, gas and steam services to municipal depart-
ments and handles monthly billings. It also administers con-
tracts for furnishing street lighting services and for operation
and maintenance of City-owned street lighting. Financing,
design and construction of City-owned street lighting improve-
ments are under the jurisdiction of the Department of Public
Works, and plans for these improvements must be approved by the
Public Utilities Commission through this Bureau. The Bureau is
financed by appropriations from municipal departments and gas
tax funds.
For fiscal year 1975-76, the Department administered budgeted
funds for all purposes as follows:

PLANS FOR THE NliAR FUTURE
Finns for future Ilctcli Hetchy construction are included in the
City's current Capita] Improvement Plan.
Projects which will be added next year will include the
following:
Cherry Eleanor Pumping Station
We have studied the possibility of installing pumps at the
Cherry end of the Cherry Eleanor Tunnel. This study determined
that it was economically feasible to capture, for electrical
generation, water which presently spills at Lake Eleanor during
the runoff season. Preliminary design work will commence this
year, while the necessary permits and approvals are being
obtained.
Moccasin Powerhouse Bypass
Studies are planned to make improvements on Rattlesnake Creek
and Rig Jackass Creek to permit the discharge of water from
Priest Reservoir into the fletch Hetchy Aqueduct for use in
times of emergency when Moccasin Powerhouse is not operative.

HETCH 1IETCHY WATER AND POWER SYSTEM
REVENUE AND EXPENDITURES
Revenue from Ketch Ketchy Water and Power operations is derived
principally from two sources:
1. Sale of electric power and energy to San Francisco Municipal
departments, Modesto and Turlock Irrigation Districts in
the San Joaquin Valley, and seven industrial customers.
Kaiser Cement f( Gypsum Corporation Santa Clara County
Kaiser Aluminum d, Chemical Corporation Santa Clara County
Lockheed Missiles and Space Company, Santa Clara County
Tnc .
General Motors Corporation Alameda County
IBM Corporation Santa Clara County
Liquid Air, Inc. Alameda County
Norris Industries, Riverbank Stanislaus County
2. Sale of water to the San Francisco Water Department.
POWER SALES
Gross sale of electric energy amounted to $20,224,183, up from
$18,484,718 during 1974-75. Although this revenue appears to
be a new record, it does not have the same significance as the
record revenue of last year. The reasons are not so obvious
without knowing the following:
(1) Much of the increase is due to the very large amount
of supplementary power and energy which City had to
purchase for resale and which was resold to the
customers at substantially the same high price at
which it was purchased.
(2) The offset to last year's record revenue in terms of
expenditure for supplementary power and energy was
only $99,734, whereas this year the offset is
$4,389,319. Therefore, from the standpoint of net
earnings, the department finds itself in a much less
profitable financial position than that of last year.
Power and energy delivered to all City Departments increased
1.9% over the previous year, mainly the result of increased
consumption at the San Francisco General Hospital where addi-
tional power for construction of the new facilities nearly
doubled the total requirements of 11,091,942 kilowatthours for
1974-75. Consumption at the Airport, usually the single largest
energy consumer among the City departments, has remained sub-
stantially the same as 1974-75. The requirements for the San
Francisco Water Department have again increased 9.31, reflecting
more pumping required by the drought condition. The Municipal
Railway showed a decrease of 12.21 in annual consumption over
the previous year, largely as a result of the Muni shutdown
during the City employees' strike.
Power and energy delivered to Modesto Irrigation District,
Hetch Hetchy's largest power customer, and to Turlock Irrigation
District, the third largest, increased by 17.71 and 13.6%
respectively this year. These increases in purchases clearly
reflect the dry year operation of the Districts' own plant where
power is derived from water stored behind Don Pedro Dam.
The hope of exceeding the record generation of 1974-75 was
effectively shattered by the drought and the strike. Instead,
the opposite was achieved with the lowest production recorded
in seven years of operation of the present project. By
comparison, the 1975-76 total output of 1,640,671,000 kilowatt-
hours is 20% less than the record output of 2,057,609,000
kilowatthours for 1974-75.
Hetch Hetchy power is sold to City Departments at cost, repre-
senting a saving to taxpayers for 1975-76 of approximately $3.2
million compared to the cost if supplied by the local investor-
owned utility.
One of the benefits resulting from the June 24, 1975 Amendment
Agreement witli the Pacific Cas and Electric Company for wheeling
Hetch Hetchy power to City's municipal customers was the reduc-
tion in energy which City has to supply to compensate the
Company for losses incurred in transmission and distribution.
The data for 1975-76 indicates that 33,248,681 kilowatthours
was delivered to the Company for this purpose, almost 41,000,000
kilowatthours less than that required under the old agreements.
This reduction in losses when sold to industrial customers at
prices effective during the year returned to the City additional
revenue in excess of $650,000.
In last year's annual report, it was estimated that the new
electric power rates which were scheduled to go into effect
July, 1975 would increase Hetch Hetchy's power revenue for 1975-
76 from sales to the municipal customers (including resale to
Airport tenants) by one million dollars. Comparison of results
for 1974-75 and 1975-76 has confirmed the accuracy of this
prognostication. Another revision of the rates is scheduled
for action by the Public Utilities Commission in July 1976.
Adoption of the proposed rates will boost revenue from sales to
private consumers and municipal users another $900,000 in the
upcoming fiscal year.
August 1975 marked the first month of higher rates for Hetch
Hetchy power sold to the Modesto and Turlock Irrigation Districts
under signed agreements with them dated May 22, 1973 and
November 6, 1972 respectively.
WATER SALES
This past year, revenue from sale of water and standby service
to the San Francisco Water Department was $6,550,000, $428,000
less than cost to Hetch Iletchy.

During the year, 70,086,900,000 gallons of water were diverted
from the Tuolumne River watershed through the Hetch Hetchy
Aqueduct to the San Francisco Water Department, representing
71" oT the City's total customer consumption. In addition,
237,693,456 gallons were delivered to the United States
Atomic Lnergy Commission at Mocho Shaft of the City's Coast
Range Tunnel for use at the Lawrence Radiation Laboratory at
Livermore; 49,306,396 gallons were delivered to Groveland

OF] R MING AND MAINTENANCE - MOCCASIN DIVISION
IIPI.M POWERHOUSE UNIT NO. 2 GENERATOR
At approximately D842 hours on Sunday, January 25, 1976, the
13,800 volt stator winding of Generator No. 2 at Dion R. Holm
Powerhouse failed. Preliminary investigation indicated that
approximately 8 of the 216 coils had heen damaged. However,
detailed examination following removal of the rotor assembly
disclosed that a total of 16 coils would have to be replaced.
Several of these coils were still functional, but dc high
voltage testing showed that they would probably fail in a short
time and were therefore deemed unacceptable for continued use.
Portions of insulation on 4 field poles were also damaged by
hot metal splatters from the stator windings when the failure
occurred, requiring re-insulation of the affected area. All
repair work was performed by departmental personnel, with
supervision provided by the field engineers from All is-Chalmers ,
the generator manufacturer. The repairs were completed and the
generating unit returned to service by the middle of March.
A board of inquiry consisting of the senior electrical engi-
neering staff members was formed to investigate the failure for
cause and to recommend corrective measures. A final report is
expected to include analyses and possible solutions to this
maintenance problem whereby the reliability of the equipment
can be improved .
CHERRY DAM HOI, LOW JET VALVE RliPAIRS
The Machine Shop repaired one of the two 60 -inch valves used to
release water from Lake Lloyd. The valve was leaking badly and
water had gotten into the operating mechanism. If allowed to
remain in place, it would have been necessary to replace the
valve in a short period of time. It was necessary to build up
and machine the body and plug seats, replace a brass bushing,
a leather packing and two thrust bearings. Other miscellaneous
repairs were made to broken or defective parts. The Mechanical
I.ngineering Section provided engineering and procurement assis-
tance to the Machine Shop, including inspection of work done to
the plug seat by a local shop. At the end of the fiscal year,
repairs were nearing completion and the valve will be available
for use during the next runoff season.
LARNER JOHNSON RliLI EF VALVE NO. 2 AT SAN JOAQUIN VALVE HOUSE
The relief valve on Pipeline No. 2 at the San Joaquin Valve
House was removed from service during pipe cleaning and painting
(HH-511R). The machine shop used this time to completely
rebuild the valve including braising and remachining the seats.

Oril RAT I ON AND MAINTENANCE - TRANSIT POWER DIVISION
The Transit Tower Division is responsible for supplying the 600
volt direct current power that is necessary to operate the
strertcars and trolley coaches of the San Francisco Municipal
Ra i 1 way .
The Transit Power Division is composed of two sections - the
Motive Power Section and the Overhead Lines Section.
Motive Power Section
11!
The Motive Power Section operates and maintains seven sub-
stations which convert electric power from 12,000 volts
alternating current to 600 volts direct current by means of
motor-generators, synchronous converters, and mercury arc
rectifiers. (See Appendix Table 3 for statistical data.)
Motive Power is also responsible for maintaining the electric
motors and associated control equipment for operating the
cable-winding machinery located in the Cable Car Powerhouse at
Washington and Mason Streets. In addition, Motive Power does
periodic inspection, cleaning, adjusting and repairing the
streetcar and trolley coach recorders at Central Control of the
Municipal Railway. The substations operate 24 hours per day,
36 5 days per year.
In anticipation of the need to assume responsibility for eigh-
teen new substations, this section perused and commented on the
wiring and control schemes proposed for these stations.
A new mimic board showing the new stations in schematic form
was constructed and installed at the Rryant Substation. As new
automatic stations are completed and become operational, they
will be monitored and controlled from this remote location.
Since Outer Mission and West Portal Stations are presently
unmanned, controls for these stations were designed and
installed on this new mimic hoard. This new status display
and control board will continually be augmented with new
automatic station controls until such time as it shall be super-
seded by a more sophisticated and flexible Supervisory Control
System.
Overhead Lines Section
The primary function of the Overhead Lines Section is to main-
tain in satisfactory operating condition the trolley wire over-
head facilities and the electric distribution system which
conveys power to it. This electric distribution system consists
of both overhead lines and underground cables.
17 -
Secondary functions include the maintenance of the Municipal
Railway Signal Systems and the electric light and power systems
of all Municipal Railway buildings.
During the fiscal year 1975-76, the Overhead Lines Section
responded to 3606 emergency calls. In addition to emergency
calls, this section had a regular and extensive maintenance
program for overhauling all overhead and underground facilities.
This section operated with three shifts per day, seven days a
week. Monday through Friday, the normal workday shift was from
8:00 a.m. to 3:30 p.m. with a two-man emergency crew on the
"swing" or evening shift (3:30 p.m. -10:30 p.m.) and the grave-
yard shift (1:00 a.m. -8:00 a.m.).
On Saturdays, Sundays and holidays a two-man emergency crew was
available on each of the three eight-hour shifts; midnight to
8:00 a.m., 8:00 a.m. to 4:00 p.m., and 4:00 p.m. to midnight.
Overhead and underground facilities were systematically
inspected, and worn or damaged parts were replaced before they
could cause accidents or malfunction of equipment.
A considerable amount of damage to overhead facilities was
caused by trolley coaches de-wiring and snagging their poles in
the overhead facilities and tearing them down, or by breaking
the spans with the flaying poles. Such damage was repaired at
no cost to the Municipal Railway. Other parties who damaged
our facilities were billed for the cost of repairs. This
included damage to overhead facilities caused by high loads on
trucks or careless operation of crane equipment and damage to
underground feeder cables by contractors digging into our duct
lines. During 1975-76, responsible parties were billed for 7
damage cases totalling $3,728.53. The Overhead Lines Section
also performed work for building owners and contractors under
work orders amounting to 18 jobs totalling $44,183.13. This
work included moving trolley poles to accommodate driveways;
relocating trolley poles and feeders to permit construction of
new buildings; temporarily removing trolley wires and feeders
to permit passage of high loads: and shifting of trolley wires
and feeders for various excavations.
The Overhead Lines Section engaged in many other activities of
a related nature which it is especially equipped to perform.
These additional, duties included repairs, maintenance and
construction of electrical systems in Muni's car barns, offices
and shops ; welding and rebuilding of worn overhead lines special
work; making and rebuilding parts for switches, warning block
signals, car recorders, and strand alarms for the cable car
system; installing mobile radio equipment; installing streetcar
and bus stop signs and public information signs.
In Marcli 1976 the section curtailed operations for a six week
period during a labor dispute involving city Craft workers.

ENGINEERING DIVISION
The Engineering Division of Hetch Hetcliy Water and Power provides
engineering services for the Hetch Hetchy Project and the Transit
Power Division. These services include the preparation of
studies, reports, cost estimates, and plans and specifications
for new construction, for replacement of structures and for items
of major maintenance. Surveying, inspection of construction,
contract administration and payment recommendations are provided
for all construction work under Hetch Hetchy Water and Power.
Work of unusual magnitude or which requires special knowledge
and expertise is done by engineering consulting firms which have
the necessary manpower and qualifications. The Engineering
Division is organized into five main sections: Structural and
Civil, Electrical, Mechanical, Architectural, and Construction.
During the year, plans and specifications were prepared for the
following work to facilitate and maintain Hetch Hetchy operations:
III' -4 5 4 - Reconstruct Moccasin Sewage Disposal System.
A package sewage treatment plant producing an odorless effluent
and sludge has been planned to replace the existing septic tank
system. This project is a carryover from last year due to the
slowness to acquire approval for the Federal "Clean Water Grant"
which we reapplied for last year. Conceptual approval has been
received. The EIR and the Project Report received approval from
the State Water Resources Control Board, and we are now awaiting
Federal EPA approval. The Hughes site for the effluent sprinkler
field was purchased during the year.
HH-4 77 - Moccasin Penstock Valve House.
A contract was let for the construction of a steel frame struc-
ture to enclose the butterfly valves at the head of Moccasin
Penstock. This structure will provide protection and security
for the valves.
HH- 511R - San Joaquin Pipeline No. 2, Repair Lining.
A contract was let for cleaning the interior of the pipe and
applying a coal-tar lining. This work was necessary because
the existing cement mortar lining, which protects the steel pipe
from corrosion, has been softened by action of the soft water
and the invert is being eroded away.
HH-512 - San Joaquin River Valve House, Repairs and Piping.
Under this contract, which was completed during the year, new
sump pumps and related piping were installed at the San Joaquin
River Valve House. Also, under this contract, a leaking manifold
at the valve house was repaired.

HH- 51 4 - Moccasin Administration Building, Replace Heating
System.
The plans and specifications to replace the existing oil burning
steam heating system and bring the electrical service at the
building up to code were completed and bids opened this year.
The existing heating system had become expensive to maintain
and operate because of its age and its use of fuel oil. The
replacement of the oil by electric heating necessitated increas-
ing the capacity of the building electrical system, and improv-
ing it to meet code requirements.
HH-539 - Repair and Taint Concrete Trolley Poles (Van Ness
Avenue) .
A contract has been let to repair and paint concrete trolley
poles on Van Ness Avenue. This work is part of a program to
rehabilitate all trolley poles in the City.
HH- 545 - Repair, Reroof Hetch Hetchy Buildings, Moccasin and
Early Intake.
A contract was let for the reroofing of the Machine Shop and
five (5) cottages at Moccasin; reroofing Kirkwood Powerhouse at
Parly Intake, and replacement of parapet flashing and construc-
tion of joint flashing at Holm Poiverhouse near Parly Intake.
HH- 5 5 5 - Replace, Repair and Paint Steel Trolley Poles (Mission
Street) .
Contract plans and specifications have been completed to
replace, repair and paint steel trolley poles on Mission Street.
The contract is scheduled to start in September 1976. This
work is part of a continuing program to rehabilitate all trolley
poles in the City.
HH-554 - Construction of #47 Trolley Coach Loop at Army Street.
At the request of the Municipal Railway, a contract was let to
restore the terminal loop of the #47 trolley coach line to Army
Street. Several years ago the route was shorted to turn back
at 25th Street in order to facilitate the construction of the
freeway interchange at Army Street and Potrero Avenue. The
Department of Public Works funded the project.
HH- 5 56 - Claribel Lateral Timber Bridge.
A contract was let for the construction of a timber bridge to
replace an existing wood plank bridge across the Oakdale
Irrigation District's lateral that has collapsed. The bridge
provides access for maintenance and inspection along our right-
of-way.

BUREAU OF LIGHT, HEAT AND POWER
STREET LIGHTING
General
The lighting of public streets within the City of San Francisco
is provided by facilities which are, on a City-wide basis, 43.51
owned by the City; 54.7s owned by the Pacific Gas and Electric
Company; and a small percentage, 1.81, jointly owned. In the
underground areas, where the economic advantage of City ownership
is greatest, 81.31 of the lights are City-owned. Five years ago,
the corresponding figure was 74.41.
In fiscal year 1933-34, the cost for street lighting was $1.25
per capita; last year, with approximately thirty times as much
light on the~streets and public thoroughfares, the cost per
capita was approximately $1.85. ~
Maintenance and repair of City-owned installations was performed
under two contracts. One provided for group replacement of
lamps in accordance with schedules developed by the Bureau. A
second contract covered work required for repair of damaged and
defective equipment, painting and miscellaneous maintenance.
Under contract, the Pacific Gas and Electric Company furnished
street lighting service as directed, including the furnishing,
maintenance and operation of Company-owned facilities. Certain
services were provided also for City-owned facilities, including
switching and control, replacement of individual lamps and
globes, and emergency work required during other than normal
working hours.
Electric energy for all City and Company-owned streetlight opera-
tion was supplied by the Hetch Hetchy power system.
Engineering
The Bureau reviews, recommends changes, approvals or rejections
of, and correlates all street lighting installations, including
that done by the Department of Public Works, the Pacific Gas and
Electric Company, the State of California, subdividers , etc.
During the fiscal year 1975-76, 19 street lighting contracts,
involving a total of 819 new streetlights, were approved by the
Public Utilities Commission. Plans were submitted only after
careful checking to determine that illumination will exceed the
minimum requirements established by the American National
Standards Institute; and that all materials used, and manner of
installation, meet with the applicable local, state and federal
rules, regulations and statutes governing the installation of
electrical works.

BUREAU OF LIGHT, HEAT & POWER
REVENUES AND EXPENDITURES
FISCAL YEAR 1975-1976
Operation and Maintenance
As of June 30, 1976, a total of 37,378 City-owned and Company-
owned streetlights were in service to the public streets, parks,
viaducts, overcrossings , tunnels and underpasses. A summary of
the number and type of units in service at the end of the fiscal
year is shown in Appendix Table.
A total of $1,326,226 was expended for operation, maintenance,
and repair of the street lighting system. Of the total cost,
$12,649 was paid by the State for its share of the operation and
maintenance of street lighting at intersections on City streets,
which are part of the State Highway system.
During the fiscal year, there were 114 accidents involving damage
to City-owned street lighting property. Investigation was made,
as soon as possible, to remove hazards to the public and obstruc-
tions to traffic. Total cost of repairs to damaged City-owned
street lighting property was $73,125. Every effort was made to
secure reimbursement for damages incurred from responsible
parties. Previous experience indicates that approximately three-
fourths of the repair costs will be recovered.
Complaints
During the year, 48 complaints requiring field investigation
were received and acted upon. These complaints concerned
inadequate illumination, objectionable glare in windows, and
requests for temporary and permanent relocation of street
lighting poles.
Improvements
During the fiscal year 1975-76, a total of 868 new City-owned
streetlights were placed in service at a cost of $724,798.
Improvements were financed by State Gasoline Tax and the 1964
and 1972 Street Lighting Bond Issues as indicated in Appendix
Tables 16 and 17.

This report is respectfully dedicated to
Hetch Hetchy employees, past and present,
whose devoted and conscientious efforts
have made possible these accomplishments
for San Francisco.
O'SHAUGHNESSY DAM AND HETCH HETCHY RESERVOIR
showing the effects of the drought in February, 1977.
HIGHLIGHTS
From the parched Redwood forests of the north state to the blazing
deserts of the south, the one single aspect that dominated all of
the water and power systems in California during the fiscal year
is an unprecedented drought and its devastating impact. For the
Hetch Hetchy Water and Power System, whose hydroelectric genera-
tion is totally dependent on water, and whose viability as a going
concern is principally dependent on power revenue, the year has
been a particularly difficult one financially.
The drought had its beginning in the winter of 1975-76 when lack
of precipitation and meager snowmelt resulted in only 605,388
acre-feet of runoff into Hetch Hetchy Reservoirs during the spring
of 1976, or 53 percent of normal. The second dry year, 1976-77,
resulted in even less runoff during the past spring, totaling only
333,504 acre-feet, or 29 percent of normal. These record low
inflows in successive years have left the three reservoirs in our
mountain watersheds at less than 45 percent of capacity at the
end of the report year.
1 -
Anticipating that the drought might continue into a second year,
the Lower Cherry Aqueduct was reconditioned in the fall of 1976
in the event that water supply to the Hetch Hetchy Aqueduct would
need to be supplemented with water from Cherry Reservoir. This
turned out to be a farsighted move when drought conditions dic-
tated shutting down Dion R. Holm Powerhouse and diverting this
water into the aqueduct to the Bay Area in October 1976.
To further conserve water in our reservoirs against future public
need, a request was submitted to the Secretary of the Interior,
in March 1977, for permission to reduce fish releases from
0' Shaughnessy Dam. So far, the Secretary has not advised us of
any decision in the matter.
Based on the precipitation record for the water year commencing
October 1, 1976, and the result of snow surveys conducted on our
mountain watersheds, the San Francisco Public Utilities Commission
instituted a mandatory 25 percent reduction in system water
consumption. The reduction was put into effect May 1, 1977, in
order to insure the ability of the Hetch Hetchy systems to meet
the needs of the San Francisco Water Department and its service
area during the continuing drought.
Comparing the amount of electric energy generated this year against
that of previous years, the adverse impact of the drought is
apparent. As generation was reduced to about 35 percent of normal,
the resulting revenue available for supplying the cash flow for
operating and maintaining the department was also reduced in
roughly the same proportion. This necessitated rescinding many of
the capital improvement projects scheduled for the year.
In spite of the above, work progressed on the federally assisted
Power Improvement Program for the rehabilitation of the Municipal
Railway transit power system. As of the end of the fiscal year,
approximately $26.5 million has been expended or encumbered. The
professional services contracts for engineering design are 90 per-
cent completed. Twenty-seven contracts for construction work and
material purchases have been completed and twenty-two are currently
in progress. Electrification of the Market Street Subway and Twin
Peaks Tunnel is nearly completed. Ten of the eighteen substations
are under construction, with three completed and in service.
Thirty miles of the eventual fifty miles of underground duct lines
are completed or under construction. Approximately 35 percent of
the underground feeder cable has been installed, and an additional
20 percent is on order for delivery to current installation
contractors. The conversion of the streetcar overhead trolley
system for pantograph operation is progressing with all work on
the "K" Line under construction; the "N" Line ready for bid; and
the "J", "L" and "M" Lines in the final design stages.

HETCH HETCHY ORGANIZATION AND FUNCTIONS
Under policies established by the San Francisco Public Utilities
Commission, the HETCH HETCHY WATER AND POWER DEPARTMENT and the
BUREAU OF LIGHT, HEAT AND POWER serve the City and County of
San Francisco in the dual function of operating department and
service bureau.
Hetch Hetchy is a municipally-owned system of storage reservoirs
and aqueducts which collects water from the Tuolumne River water-
shed and delivers it to the San Francisco Water Department. As
a by-product of falling water, Hetch Hetchy operates and maintains
hydroelectric generating stations and high voltage transmission
lines for the production and distribution of electric energy.
Through its Transit Power Division, Hetch Hetchy has funded,
operated, maintained and provided improvements for the electric
facilities of the San Francisco Municipal Railway since July 1,
1969.
In order to handle this additional responsibility, Hetch Hetchy
assumed control of the equipment and personnel of the Overhead
Lines and Motive Power Sections of the Municipal Railway.
All of Hetch Hetchy' s expenses, including those of the Transit
Power Division, are supported by water and power revenues.
The Bureau of Light, Heat and Power administers contracts for
furnishing electric, gas and steam services to municipal depart-
ments and handles monthly billings. It also administers contracts
for furnishing street lighting services and for operation and
maintenance of City-owned street lighting. Financing, design and
construction of City-owned street lighting improvements are under
the jurisdiction of the Department of Public Works, and plans for
these improvements must be approved by the Public Utilities
Commission through this Bureau. The Bureau is financed by appro-
priations from municipal departments and gas tax funds.
For fiscal year 1976-77, the Department administered budgeted
funds for all purposes as follows:

HI-TCH HETCHY WATER AND POWER SYSTEM
REVENUE AND EXPENDITURES
Revenue from Hetch Hetchy Water and Power operations is derived
principally from two sources:
1. Sale of water to the San Francisco Water Department
2. Sale of electric power and energy to San Francisco Municipal
departments, Modesto and Turlock Irrigation Districts in the
San Joaquin Valley, and seven industrial customers:
Kaiser Cement § Gypsum Corporation Santa Clara County
Kaiser Aluminum § Chemical Corporation Santa Clara County
Lockheed Missiles and Space Company, Inc. Santa Clara County
General Motors Corporation Alameda County
IBM Corporation Santa Clara County
Liquid Air, Inc. Alameda County
Norris Industries, Riverbank Stanislaus County
WATER SALES
This past year, revenue from the sale of water and standby service
to the San Francisco Water Department was $8 million.
POWER SALES
Gross sale of electric energy was $43,341,973, up from $19,693,525
during 1975-76. This doubling of revenue is deceiving, since the
increase does not represent extra return on project investments
for the following reasons:
1. The increase is principally due to the record-breaking amount
of supplementary power and energy which City had to purchase
for resale, on account of the drought, and which was resold
to the customers at substantially the same high price at which
it was purchased.
2. The offset to this year's so-called record revenue, in terms of
expenditure for supplementary power and energy, is $33,921,500
instead of the $2,100,000 budgeted, leaving only $9,420,473 in
net revenue from gross, a far cry from the record net of over
$18 million for 1974-75.
Power and energy delivered to City Departments increased 2.0 per-
cent over the previous year, about the same rate as in 1975-76.
The City department mainly responsible for this increase is the
San Francisco International Airport. Consumption at the Airport,
the single largest energy consumer among the City Departments,

HETCH HETCHY REVENUES
AND EXPENDITURES
FISCAL YEAR 1976-77
has increased by 3.2 percent, indicative of a resurgence of
construction and expansion activities. Requirements for the
Municipal Railway appear to have increased by 9.5 percent over
the previous year. This is not a valid comparison, of course,
because of last year's low consumption due to shutdown of the
public transportation system during the 38-day employees' strike.
Power and energy delivered to Modesto Irrigation District, Hetch
Hetchy's largest power customer, and to Turlock Irrigation District,
the third largest, increased by 17.2 percent and 37.9 percent
respectively this year. These increases are directly related to
the drought. The storage in Don Pedro Reservoir, upon which the
two Districts are dependent for generation and irrigation needs,
has been going down steadily and the Districts have been extremely
careful in using this precious and meager resource. Since Hetch
Hetchy is in the same predicament, 86 percent of the power deliv-
ered to the Districts by Hetch Hetchy had to be supplied from
supplementary power and energy purchased from the Pacific Gas and
Electric Company.
Total generation of 710,002,000 kilowatthours for the report year
from the project's three plants (the lowest production since 1969)
amounts to 43 percent of the output of 1,640,471,000 kilowatthours
in 1975-76. The financial strength of the Department resulting
from this decline in electric energy generation has been severely
impaired. If current conditions continue, additional shortfall
in operating revenue in the upcoming fiscal year can be anticipated.
Hetch Hetchy power is sold at cost to City Departments for munici-
pal purposes, representing a saving to taxpayers for 1976-77 of
approximately $4 million, compared to the cost if supplied by the
local investor-owned utility at rates which include a "fuel cost
adjustment" to account for the additional costs brought on by the
unending price increases in oil, gas and coal fuel used for
electric generation. Beginning September 1976, revised rates for
Hetch Hetchy power, approved by the Commission on July 13, 1976,
became effective for private consumers and municipal users. The
higher rates boosted power revenue from these sources by nearly
$1 million in the fiscal year. This is just another step in our
continuing effort to base our power rates on the value of power
in the market place, in order to maximize the return of the power
that is produced from the Hetch Hetchy system. In a fiscal year
where generation is at a record low, this increase helped to
somewhat ease the economic dislocation brought on by the reduced
generation.

REVENUE FROM SALE OF ELECTRIC ENERGY
Department has been investigating the feasibility of a weather
modification program. The goal is to increase precipitation by
cloud seeding of appropriate storms in the area. Preliminary
data indicate that our effort should be directed to the Cherry
Watershed. As an initial step to bring this program to fruition,
plans are under way to hire expert consultants for the preparation
of an Environmental Impact Report.
On October 22, 1976, the City and County of San Francisco, through
the Public Utilities Commission, together with the Modesto and
Turlock Irrigation Districts, submitted an "Amended Application
for Preliminary Permit, Clavey-Wards Ferry Project" to the Federal
Power Commission. The application was made in order that the City
and the Irrigation Districts might secure and maintain priority
for a license under the Federal Power Act. The proposed project
consists of three small dams and related facilities designed to
harness the unused power potential of the Tuolumne. They would be
situated on the upper reaches of the river below the City's Dion R.
Holm and Robert C. Kirkwood Powerhouses and upstream from Don
Pedro Dam. It is estimated that the project has a capability of
generating 400 megawatts of power as well as a new water supply of
11,900 acre-feet. However, actual development will depend on the
outcome of a study by federal agencies for possible inclusion of
this portion of the river in the federal wild and scenic river
system.
OPERATION AND MAINTENANCE
On Sunday, November 7, 1976, at approximately 0822 hours, the
13,800 volt metal-clad switchgear unit through which power is
supplied to the 2,500 kVA Ridge Line transformer from Generator
No. 2 at Dion R. Holm Powerhouse failed during routine testing
of a protective device. The failure resulted in destruction of
the circuit breaker element and related appurtenances. However,
service to the Ridge Line was promptly restored by connecting it
to the Mather Line, which is supplied from Robert C. Kirkwood
Powerhouse. Necessary replacements were purchased from General
Electric and installed by Department personnel with final adjust-
ment and testing performed by field engineers from General
Electric. All work was completed and service to the Ridge Line
reverted to Dion R. Holm Powerhouse on June 3, 1977.
WATER PRODUCTION AND TRANSMISSION
Precipitation recorded for the year at our measuring stations was
52 percent of the long term average. Much of this amount fell
during the normally dry summer months and did not run off.

OPERATION AND MAINTENANCE - TRANSIT POWER DIVISION
The Transit Power Division is responsible for supplying the 600
volt direct current power that is necessary to operate the street-
cars and trolley coaches of the San Francisco Municipal Railway.
The Transit Power Division is composed of two sections - the
Motive Power Section and the Overhead Lines Section.
Motive Power Section
The Motive Power Section operates and maintains ten substations
which convert electric power from 12,000 volts alternating current
to 600 volts direct current by means of motor-generators, synchro-
nous converters, mercury arc rectifiers and silicon rectifiers.
(See Appendix Table 3 for statistical data.) Motive Power is
also responsible for maintaining the electric motors and associated
control equipment for operating the cable-winding machinery located
in the Cable Car Powerhouse at Washington and Mason Streets. In
addition, Motive Power periodically inspects, cleans, adjusts and
repairs the streetcar and trolley coach headway recorders at
Central Control of the Municipal Railway. The substations operate
24 hours per day, 365 days per year.
In anticipation of the need to assume responsibility for eighteen
new substations being built by the Power Improvement Program
(reported elsewhere in this report) , this section perused and
commented on the wiring and control schemes proposed for these
stations. The first of the new electrical substations, Civic
Center Station, was placed in revenue service in December of 1976.
A commissioning ceremony was held by Mayor George Moscone who
dedicated this first station to the service of the citizens of
San Francisco.
A new mimic board showing the new stations in schematic form was
constructed and installed at the Bryant Substation. As each new
automatic station is completed and becomes operational, it will
be monitored and controlled from this remote location via telephone
lines. Since Civic Center, Church, Judah, Outer Mission and West
Portal Stations are presently unmanned, controls for these stations
were designed and installed on this new mimic board. This new
status display and control board will continually be augmented
with additional automatic station controls until such time as it
shall be superseded by a more sophisticated and flexible Supervisory
Control System.
Overhead Lines Section
The primary function of the Overhead Lines Section is to maintain
in satisfactory operating condition the trolley wire overhead
facilities and the electric distribution system which conveys
power to it. This electric distribution system consists of both
overhead lines and underground cables.
-11
Secondary functions include the maintenance of the Municipal
Railway Signal Systems and the electric light and power installa-
tions at all Municipal Railway buildings.
During fiscal year 1976-77, the Overhead Lines Section responded
to 3,943 emergency calls, an increase of 8 percent over the prior
year. In addition to emergency calls, this section performed a
regular and extensive ongoing maintenance program. All overhead
and underground facilities were systematically inspected and all
worn or damaged parts that could cause accidents or equipment
malfunctions were replaced. This section also operates an
emergency crew 24 hours a day year round, including all holidays.
The main work crew normally worked on the day shift but occasion-
ally was assigned to night work to overhaul facilities during the
hours Muni trolleys and streetcars do not run.
A considerable amount of damage to overhead facilities was caused
by trolley coaches de-wiring and snagging their poles in the
overhead facilities and tearing them down, or by breaking the spans
with the flaying poles. Such damage was repaired at no cost to
the Municipal Railway. Other parties who damaged our facilities
were billed for the cost of repairs. This included damage to
overhead facilities caused by high loads on trucks or careless
operation of crane equipment and damage to underground feeder
cables by contractors digging into our duct lines. During 1976-77,
responsible parties were billed for 9 damage cases totaling
$17,246.41. The Overhead Lines Section also performed work for
4 building owners and contractors under work orders amounting to
$2,994.82. This work included moving trolley poles to accommodate
driveways; relocating trolley poles and feeders to permit construc-
tion of new buildings; temporarily removing trolley wires and
feeders to permit passage of high loads; and shifting of trolley
wires and feeders for various excavations.
The Overhead Lines Section engaged in many other activities of a
related nature which it is especially equipped to perform. These
additional duties included repairs, maintenance and construction
of electrical systems in Muni's car barns, offices and shops;
welding and rebuilding of worn overhead lines special work; making
and rebuilding parts for switches, warning block signals, car
recorders, and strand alarms for the cable car system; installing
mobile radio equipment; installing streetcar and bus stop signs
and public information signs.

A package sewage treatment plant
has been planned to replace the
existing septic tank system. This
process is a carryover from last
year due to the lengthy process
required to obtain approval for a
federal "Clean Water Grant". State
and federal permission to begin
preparation of final plans and
specifications was given in Septem-
ber, 1976. Approval of the final
plans and specifications was ob-
tained in March, 1977. The con-
struction contract has subsequently

HH-514 - Moccasin Administration Building, Replace Heating System
Under this contract, completed during the year, the old heating
system, using costly fuel oil, was replaced by a new electrical
heating/ventilating system. In addition, extensive electrical
improvements were made to bring the existing electrical system up
to code requirements, and extensive plumbing and architectural
improvements were also made.
HH-54 9 - Bryant Substation and Power Control Center
The Power Control Center (part of the Power Improvement Program
described elsewhere in this report) was originally to be installed
in the existing Bryant Substation building. When engineering
investigations of this 1904 building revealed that it did not meet
seismic standards, it was determined to construct a new building
to house both the Control Center and the new substation. The
Control Center portion of the building will accommodate the facili-
ties for remote supervisory control of the eighteen new automatic
substations that will provide electric power for the Municipal
Railway. The design of the substation portion of the building
was performed by our consultants under the Power Improvement
Program. The design of the Power Control Center portion of the
building has nearly been completed by Hetch Hetchy personnel.
The design of the facility has received approval of the Art
Commission and a City Planning Commission Environmental Impact
Report determination of no significant effect on the environment.

In anticipation of a continued drought, an emergency construction
contract was let to rehabilitate the Lower Cherry Aqueduct in
order to supplement the water supply to Hetch Hetchy Aqueduct with
water from Lake Lloyd and Lake Eleanor. This three mile long
aqueduct was originally constructed in 1917, had not been used
since 1960, and was in poor condition. The contract has been
completed and diversion of water began in November 1976 with a
capability of supplying approximately 130 mgd into the Hetch
Hetchy Aqueduct at Early Intake.

C) Equipment Purchase
The substation equipment manufacturer, ITE-Gould, completed
production on the $5,896,000 purchase contract.
Review of shop drawings submitted by ITE-Gould was
completed.
Negotiations were conducted with ITE-Gould for a contract
modification to provide additional equipment for Laguna
Honda Substation. The second rectifier, transformer and
related switchgear to be purchased will provide power
reliability in the Twin Peaks Tunnel. This addition to
the Project was approved by UMTA in the Grant Amendment.
Deliveries of equipment under the purchase contract were
virtually completed. Equipment for Laguna Honda, Judah
and Downtown Substations were received by the Contractors,
Herrero Brothers, Inc. (Laguna Honda and Judah) and DeNarde
Construction Co. (Downtown) and is being installed. This
completed delivery to the site for five substations. For
the remaining substations, all items of the equipment,
except for minor shortages, are on hand at the local ware-
house for later pickup by the installation contractors.
Meetings were held with factory representatives from ITE-
Gould to resolve outstanding minor problems that have
developed during installation and initial operation of
the new substation equipment.
The Service Engineer, assigned by ITE-Gould to assist
during installation and testing of the new equipment,
continued to provide assistance at Downtown, Civic Center,
Church, Laguna Honda and Judah Substations.

BUREAU OF LIGHT, HEAT AND POWER
STREET LIGHTING
General
The lighting of public streets within the City of San Francisco
is provided by facilities which are, on a City-wide basis, 44.0
percent owned by the City; 54.2 percent owned by the Pacific Gas
and Electric Company; and a small percentage, 1.8 percent, jointly
owned. In the underground areas, where the economic advantage of
City ownership is greatest, 82.4 percent of the lights are City-
owned. Five years ago, the corresponding figure was 78.3 percent.
In fiscal year 1933-34, the cost for street lighting was $1.25 per
capita; last year, with approximately thirty times as much light
on the streets and public thoroughfares , the cost per capita was"
approximately $2.18.
Maintenance and repair of City-owned installations was performed
under two contracts. One provided for group replacement of lamps
in accordance with schedules developed by the Bureau. A second
contract covered work required for repair of damages and defective
equipment, painting and miscellaneous maintenance.
Under contract, the
and Electric Company

Engineering
The Bureau reviews, recommends changes, approvals or rejections
of, and correlates all street lighting installations, including
that done by the Department of Public Works, the Pacific Gas and
Electric Company, the State of California, subdividers, etc.
During the fiscal year 1976-77, 14 street lighting contracts,
involving a total of 664 new streetlights, were approved by the
Public Utilities Commission. Plans were submitted for approval
> only after careful checking to determine that illumination will
exceed the minimum requirements established by the American
National Standards Institute; and that all materials used, and
manner of installation, meet with the applicable local, state and
federal rules, regulations and statutes governing the installation
of electrical works.
Operation and Maintenance
As of June 30, 1977, a total of 37,446 City-owned and Company-
owned streetlights were in service to the public streets, parks,
viaducts, overcrossings , tunnels and underpasses. A summary of
the number and type of units in service, at the end of the fiscal
year, is shown in Appendix Table 14.
A total of $1,524,286 was expended for operation, maintenance,
and repair of the street lighting system. Of the total cost,
$18,773 was paid by the State for its share of the operation and
maintenance of street lighting at intersections on City streets,
which are part of the State Highway system.
During the fiscal year, there were 127 accidents involving damage
to City-owned street lighting property. Investigation was made,
as soon as possible, to remove hazards to the public and obstruc-
tions to traffic. Total cost of repairs to damaged City-owned
street lighting property was $104,000. Every effort was made to
secure reimbursement for damages incurred from responsible parties.
Previous experience indicates that more than half of the repair
costs will be recovered.
Complaints
During the year, 40 complaints requiring field investigation were
received and acted upon. These complaints concerned inadequate
illumination, objectionable glare in windows, and requests for
temporary and permanent relocation of street lighting poles.
Improvements
During the fiscal year 1976-77, a total of 691 new City-owned
streetlights were placed in service at a cost of $1,184,878.
Improvements were financed by State Gasoline Tax and the 1964
and 1972 Street Lighting Bond Issue as indicated in Appendix
Tables 16 and 17.

HETCH HETCHY WATER AND POWER DEPARTMENT
ORAL L. MOORE - General Manager
This report is respectfully dedicated to
Hetch Hetchy employees, past and present,
whose devoted and conscientious efforts
have made possible these accomplishments
for San Francisco.
HIGHLIGHTS
In spite of a very poor first half, resulting from drought, and in spite
of rate limitations established by court order, Hetch Hetchy finished the
year with record high power revenues, both as to gross and net after
power purchases.
Starting with less than half full reservoirs at the beginning of the year,
a third dry year was very much a possibility. In order to create the
necessary funding to carry on operations in the face of potentially record
expenditures for purchased power, a substantial portion of the previously
budgeted capital improvements was rescinded. With heavy rains and snows
falling on our mountain watersheds throughout the winter, resulting in
spring runoffs which turned out to be the second highest recorded in the
last 60 years, the severe drought, which has impacted the Department's opera-
tions during the past two years ( ended and was replaced with a situation
where our powerhouses were scheduled for all-out generation during the last
half of the Fiscal Year. Combined with decreased power demands of the
Modesto and Turlock Irrigation Districts, the Increased generation permitted
Hetch Hetchy to sell much of its power at market rates in the last 6 months.
This enabled the Public Utilities Commission to transfer $6 million of the
Department's year-end surplus to the General Fund.
As noted later in the report, the remaining $3 million from this year's
surplus is earmarked for a reserve fund for protection of the City against
possible failure of current litigation involving Hetch Hetchy power rates.
To illustrate the remarkable turn-around of the last 6 months, a few selected
comparisons between the two halves of the year is revealing.

HETCH HETCHY ORGANIZATION AND FUNCTIONS
Under policies established by the San Francisco Public Utilities Commission, the
HETCH HETCHY WATER AND POWER DEPARTMENT and the BUREAU OF LIGHT, HEAT AND POWER
serve the City and County of San Francisco in the dual function of operating
department and service bureau.
Hetch Hetchy is a municipally-owned system of storage reservoirs and aqueducts
which collects water from the Tuolumne River watershed and delivers it to the
San Francisco Water Department. As a by-product of falling water, Hetch Hetchy
operates and maintains hydroelectric generating stations and high voltage
transmission lines for the production and distribution of electric energy.
Through its Transit Power Division, Hetch Hetchy has funded, operated, maintained
and provided improvements for the electric facilities of the San Francisco
Municipal Railway since July 1, 1969.
In order to handle this additional responsibility, Hetch Hetchy assumed control
of the equipment and personnel of the Overhead Lines and Motive Power Sections
of the Municipal Railway.
All of Hetch Hetchy' s expenses, including those of the Transit Power Division,
are supported by water and power revenues.
The Bureau of Light, Heat and Power administers contracts for furnishing electric,
gas and steam services to municipal departments and handles monthly billings.
It also administers contracts for furnishing street lighting services and for
operation and maintenance of City-owned street lighting. Financing, design and
construction of City-owned street lighting improvements are under the juris-
diction of the Department of Public Works, and plans for these improvements
must be approved by the Public Utilities Commission through this Bureau. The
Bureau is financed by appropriations from municipal departments and gas tax
funds.
For fiscal year 1977-78, the Department administered budgeted funds for all
purposes as follows:

HETCH IIETCIIY WATER AND POWER SYSTEM
REVENUE AND EXPENDITURES
Revenue from Ketch Hetchy Water and Power operations is derived principally from
two sources:
1. Sale of water to the San Francisco Water Department
2 . Sale of electric power and energy to San Francisco Municipal departments,
Modesto and Turiock Irrigation Districts in the San Joaquin Valley, and seven
industrial customers:
Kaiser Cement & Gypsum Corporation
Kaiser Aluminum & Chemical Corporation
Lockheed Missiles and Space Company, Tnc,
General Motors Corporation
TRM Corporation
Ltnuid Air, Inc.

WATER SALES
This past year revenue from the sale of water and standby service to the San
Francisco Water Department was $7,175 million
POWER SALES
Cross sales of electric energy was 49,971,915 t and increase of 6,629,942 from
the $43,341 ,973 for 1976-77. The increase, by itself, appears substantial, but
the significance of the increase goes beyond these numbers for the following
reasons;
(1) The offset to this year's power revenue in terms of expenditure for
supplementary power and energy is $29,561,113, down from $33,921,500,
leaving a net revenue from gross of $21,123,114 for the year as compared
to $9,420,473 for 1976-77. This new high in net revenue replaced the
record $18 million achieved in 1974-75.
(2) The increase was achieved through the sale of power and energy
generated during the months of March through June 1978 when all
project plants were in maximum production in order to take full
advantage of the record inflow and, at the same time, to delay filling
of the reservoirs, thus minimizing spill.
Power and Energy delivered to the City Departments decreased 2.1 percent over
the previous year. The City department mainly responsible for this decrease is
the San Francisco Water Department whose consumption dropped 31.3 per cent. Due
to the effectiveness of both voluntary and mandatory water rationing programs
during the drought, there wan considerably less need for pumping and filtration

AND EXPENDITURES
FISCAL YEAR 1977-78
of the domestic water supply. On the other side of the ledger, consumptions
of the Municipal Railway and the Unified School District for the year have
increased 7.5 per cent and 5 . 5 per cent respectively. The increase incurred
l>y the Municipal Railway Is directly related to the completion of the John M.
Woods Motor Coach Center and the Muni Metro Center, major facilities for the
storage and maintenance of motor coaches, streetcars and eventually the new
light rail vehicles. The magnitude of the increase incurred by the schools
(including the community colleges) is uncharacteristic of the load based on
historical records. A concerted effort in energy conservation might provide
the key to reducing this groving consumption. Besides the San Francisco Water
Department, consumption at the San Francisco international Airport also
decreased 1.8 per cent as compared to previous year. In the face of continuing
construction activities, this decrease seems to imply that energy conservation
practices by both managment and tenants might be bearing fruit.
Power and energy delivered to Modesto Irrigation District, perennially Hetch
Hetchy 's largest power customer, and to Turlbck Irrigation District, normally
the third largest but for 1977-78 the second largest, dropped 1.2 per cent and
2.6 per cent respectively this year. These decreases are directly related to
the dramatic ending of the drought which enabled the two Districts to supply
during the last 6 months over 244 million kilowatthours of energy from their
own generation as compared to 31 million kilowatthours in the first 6 months.
Total generation of 1,401,610,000 kilowatthours for the report year from the
project's three power plants represents a doubling of the 710,002,000 kilowatthours
for 1976-77 which had the unenviable distinction of being the lowest production
year since completion of the expanded system in 1969. The financial Impact of
the additional generation can best be demonstrated by a comparison of the sales
to the assigned industrial customers which are billed at current PCandE rates:
^pro kilowatthours for 1976-77 versus 210 million kilowatthours for 1977-78,
producing a revenue gain of $7.7 millions.
Two conflicting rulings rendered by U.S. District Court judges during the year
have affected our revenue from sale of Hetch Hetchy power. Both cases center
on the question whether prior approval of the Secretary of Interior is required
for rates charged by the San Francisco Public Utilities Commission for sale of
Hetch Hetchy generated power for commercial purposes. On September 15, 1977
Judge Cecil Poole, U.S. District Court for the Northern District of California,
rendered a summary judgment in favor of City in the case of City and County of
San Francisco vs. Various Airlines. Judge Poole ruled that the San Francisco
Public Utilities Commission has the legal right to set rates for Hetch Hetchy
power without approval of the Secretary of the Interior. The matter came to
issue when the Public Utilities Commission, following historical practice,
raised power rates to those prevailing in the service area in July 1975. The
airlines initially refused to pay, contending that Hetch Hetchy power rates
must be approved by the Secretary. On February 8, 1978. Judge Phillip Wilkins,
U.S. District Court for the Kastern District of California, rendered two
decisions in the case of the Modesto and Turlock irrigation Districts vs. City
and County of San Francisco. The case was initiated by the two Districts in
response to City's withdrawing of Class 3 Power (commercial power) from them
on July 1, 1976.

RFVFNIIF FROM SAI F OF Fl Ff.TRir. FNFRfiY
In favor of the City, the Judge held that the right of City to withdraw Class
3 Hetch Hetchy power and substituting it with power purchased from PGandE
involves a threshhold question of contract interpretation which, by virtue of
the arbitration clause in the contracts, must be referred to arbitration.
Against the City is the decision that the Secretary of the Interior must approve
Hetch Hetchy power rates and the City therefore is restrained from selling Hetch
Hetchy power for commercial purposes to any purchaser at rates not approved by
the Secretary. Notices of appeal have been filed by opponents of the decisions.
Even with the two cases now consolidated on appeal, resolution of the issues
appears a long way down the road.
Meanwhile, a reserve fund of $6,125 million is being established from this year's
remaining surplus and the anticipated surplus for 1978-79 to protect the City
from a substantial liability should the pending litigation be resolved against
the City.
Hetch Hetchy power is sold at cost to City Departments for municipal purposes,
representing a saving to taxpayers for 1977-78 of approximately $8 million,
compared to the cost if supplied by the local investor-owned utility at rates
which include a "fuel cost adjustment" to account for the high costs of non-
renewable fuels used for electric generation.
In a continuing effort to maximize return of the power produced from its own
system, Hetch Hetchy increased its rates for private consumers and municipal
users to the level of current market value on July 1977 and again on April 1978.
These increases would have more than doubled power revenue from the San
Francisco International Airport - from about $3 million a year to $6.9 million.
However, due to Judge Wilkin's decision as noted above, such hopeful gain was
not achieved. Under guidelines suggested by the City Attorney's office while
the injunction is being appealed, billing to the Airport tenants must revert
to the Pre- July 1, 1975 rates beginning with the month of March 1978.
SYSTEM PLANNING
As mentioned in the annual report last year about plans for initiating a weather
modification program in the Cherry watershed area to increase its water yield,
the City on December 1977 entered into a professional services contract with
Environmental Science Associates, Inc., Foster City, California, for the
preparation of an Environmental Impact Report. Steady progress is being made
on the report draft, with approximately 30 per cent completed as of the end of
the fiscal year.

WATLR PRODUCTION AND TRANSMISSION
Precipitation recorded for the year at our measuring stations was 159% of the
long term average.
During the year, 51,935, 400, 000 gallons of water were diverted from the
Tuolumne River watershed through the Iletch lletchy Aqueduct to the San
Francisco Water Department, representing 78% of the City's total customer
consumption. In addition, 199,7)3,204 gallons, down 9% from last year,
were delivered to the United States Atomic Energy Commission at Mocho
Shaft of the City's Coast Range Tunnel for use at the Lawrence Radiation
Laboratory at Livermore; 49,932,740 gallons, down 15% from 1976/77, were
delivered to Groveland Community Service District in Tuolumne County from
the Mountain Tunnel.

DELIVERIES OF WATER TO
SAN FRANCISCO WATER DEPARTMENT
OPERATION AND MAINTENANCE - TRANSIT POWER DIVISION
The Transit Power Division is responsible for supplying the 600 volt direct
current power that is necessary to operate the streetcars and trolley coaches
of the San Francisco Municipal Railway.
The Transit Power Division is composed of two sections - the Motive Power
Section and the Overhead Lines Section.
Motive Power Section
The Motive Power Section presently operates and maintains sixteen substations
which convert electric power from 12,000 volts alternating current to 600 volts
direct current by means of motor-generators, synchronous converters, mercury
arc rectifiers and silicon rectifiers. (See Appendix Table 3 for statistical
data.) Motive Power is also responsible for maintaining the electric motors
and associated control equipment for operating the cable-winding machinery
located in the Cable Car Powerhouse at Washington and Mason Streets. In
addition, Motive Power periodically inspects, cleans, adjusts and repairs the
streetcar and trolley coach headway recorders at Central Control of the
Municipal Railway. The substations operate 24 hours per day, 365 days per year.
In anticipation of the need to assume responsibility for the eighteen new
substations being built by the Power Improvement Program (reported elsewhere
in this report) , this section perused and commented on the wiring and control
schemes proposed for these stations. The first of the new electrical
substations, Civic Center Station, was placed in revenue service in December
of 1976. Subsequently, in fiscal year 1977-78, nine new substations were
placed in service: Downtown, Church, Judah, Fillmore, Carl, San Jose, Randolph,
Taraval and Laguna Honda.
A mimic board showing the new stations in schematic form was modified to
incorporate these new stations at the Bryant Substation. As each new automatic
station was completed and became operational, it was monitored and controlled
from this remote location via telephone lines, since all the new stations are
presently unmanned. The controls for these stations were designed and installed
on this mimic board. This status display and control board will continually
be augmented with additional automatic station controls until such time as it
shall be superseded by a more sophisticated and flexible Supervisory Control
System.
Overhead Lines Section
The primary function of the Overhead Lines Section is to maintain in satisfactory
operating condition the trolley wire overhead facilities and the electric
distribution system which conveys power to it. This electric distribution system
consists of both overhead lines and underground cables.
Secondary functions include the maintenance of the Municipal Railway Signal
Systems and the electric light and power installations at all Municipal Railway
buildings.
- 9 -
During fiscal year 1977-78, the Overhead Lines Section responded to 3,649
emergency calls, a decrease of 8% over the prior year. In addition to emergency
calls, this section performed a regular and extensive ongoing maintenance pro-
gram. All overhead and underground facilities were systematically inspected and
all worn or damaged parts that could cause accidents or equipment malfunctions
were replaced. This section also operated an emergency crew 24 hours a day
year round, including all holidays. The main work crew normally worked on the
day shift but occasionally was assigned to night work to overhaul facilities
during the hours Muni trolleys and streetcars do not run.
A considerable amount of damage to overhead facilities was caused by trolley
coaches de-wiring and snagging their poles in the overhead facilities and
tearing them down, or by breaking the spans with the flaying poles. Such damage
was repaired at no cost to the Municipal Railway. Other parties who damaged
our facilities were billed for the cost of repairs. This included damage to
overhead facilities caused by high loads on trucks or careless operation of crane
equipment and damage to underground feeder cables by contractors digging into
our duct lines. During 1977-78, responsible parties were billed for 11 damage
cases totaling $6,946.34. The Overhead Lines Section also performed work for
19 building owners and contractors under work orders amounting to $23,587.32.
This work included moving trolley poles to accommodate driveways; relocating
trolley poles and feeders to permit construction of new buildings; temporarily
removing trolley wires and feeders to permit passage of high loads; and shifting
of trolley wires and feeders for various excavations.
The Overhead Lines Section engaged in many other activities of a related nature
which it is especially equipped to perform. These additional duties included
repairs, maintenance and construction of electrical systems in Muni's car barns,
offices and shops; welding and rebuilding of worn overhead lines special work;
making and rebuilding parts for switches, warning block signals, car recorders,
and strand alarms for the cable car system; installing mobile radio equipment;
installing streetcar and bus stop signs and public information signs.

ENGINEERING DIVISION
The Engineering Division of Hetch Hetchy Water and Power provides engineering
services for the Hetch Hetchy Project, Transit Power Division and the Power
Improvement Program. These services include the preparation of studies,
reports, cost estimates, and plans and specifications for new construction,
for replacement of structures and for items of major maintenance. Surveying,
inspection of construction, contract administration and payment recommendations
are provided for all construction work under Hetch Hetchy Water and Power.
Work of unusual magnitude or which requires special knowledge and expertise is
clone by engineering consulting firms which have the necessary manpower and
qualifications. The Engineering Division is organized into six main sections:
Civil and Construction, Electrical, Mechanical, Architectural, Engineering
Administration, and Special Projects (Power Improvement Program).
During the year, plans and specifications were prepared for the following work
to facilitate and maintain Hetch Hetchy operations:
HH-549 - Bryant Substation and Power Control Center (Under Power Improvement
Program)
Plans and specifications for the Bryant Substation and Power Control Center,
"Construct Building and Install Equipment", was completed in January 1978.
Hetch Hetchy Water and Power and our consultants, Bechtel Incorporated have
jointly prepared the plans and specifications. The Power Control Center portion
of the building was exclusively designed by Hetch Hetchy. The building will
be constructed on vacant City property, located adjacent to the existing
Bryant Substation. The substation will supply 615 volt D.C. traction power
to Municipal Railway trolley coaches. The Power Control Center will accommodate
facilities for a shop, offices, and a power system supervisory control room.
The PUC received bids on March 2, 1978, and the responsible low bid of $1,020,000
submitted by Moore Construction of San Francisco was approved and the contract
was awarded by PUC on March 14, 1978. Construction commenced in June 1978 and
completion of project is scheduled for July 1979. The Bryant Substation and
Power Control Center will complete the new substation construction program
under the Power Improvement Program (PIP) .
HH-566 - San Joaquin Valve House - Backflow Prevention and Replacement of
Miscellaneous Mechanical Work
Contract documents were prepared to prevent contaminated and polluted river
water in Elliott Cut from entering the pipelines when they are drained for
maintenance purposes in this area. The contract also includes the replacement
of certain mechanical appurtenances at the valve house, Oakdale meter house
and on the pipelines.
HH-57_0 -_Surface West Portal and Priest Roads
A construction contract was let to resurface and seal the service roads into
West Portal and Priest Reservoir to prevent the further deterioration of these
roadways .
- 11 -
HV1-577 - OakdaleJ?ortal Sand Trap
Plans and specifications have been prepared to construct a sand and gravel
trap in the existing manifold which connects the San Joaquin pipelines to the
Foothill Tunnel. The pipelines are being subjected to unusual wear along the
invert of the pipes, caused by sand and gravel carried from the tunnel into
these pipes. This contract will eliminate this source of wear to the pipelines.
HH-591 - Cherry Road Slide Repair
Plans and specifications were prepared for repairing a slide area on Cherry
Road near Cherry aqueduct tunnel portal 2-A by stabilizing the downhill slope
and by excavating into the upslope bank to relocate a portion of the roadway
away from the slide area.
HH-593 - Paint and Repair Downtown Substation (Under Power Improvement Program)
Plans and specifications have been prepared for the painting and repairs to
the existing substation building. Work includes carbon-dust debris removal
from building surfaces that was produced by the old rotary generators.
Existing large windows on Stevenson Street will be elevated for added security.
Interior and exterior painting and installation of additional lighting fixtures
will complete the work on this operational substation.
HH-595 - Moccasin Sewage Plant, Replace Sanitary Sewer
Plans and specifications were prepared and a contract let for replacing a
portion of the sanitary sewer in Moccasin Village which has deteriorated badly
over the years. Construction is scheduled to start in July 1978.
Moccasin Powerhouse, Turbine and Bypass Bulkhead Gates. A purchase contract
was let for the fabrication of structural steel gates which are required so
that inspection or maintenance work can be performed in the discharge side
of either unit separately, while the other unit remains in service. At
present, both units must be shut down to accomplish this work. Bids were
received in November 1977 with the gates to be delivered in July 1978.
- 12 -
During the months of February and March, the Foothill Tunnel and San
Joaquin Pipelines were shut down for inspection. The following
observations were reported:
Moccasin Re-regulating Reservoir
The bypass pipe is in good condition. The entrance to the Foothill
Tunnel and Moccasin gate tower slide gate are in good condition, showing
very little leakage with the reservoir elevation at 916. 0(+).
Red Mountain Bar Wasteway
The slide gate is in good condition. The concrete mortar lining D/S of
the gate had eroded in a number of places but were repaired during the
shutdown.
Foothill Tunnel - Red Mountain Bar Wasteway to Oakdale Portal
The Tunnel from Rock River Lime Treatment Plant to Red Mountain Bar is
in good condition; no slides nor blockages, but some water infiltration.
The Tunnel from Rock River Lime Treatment Plant to Oakdale Portal is in
excellent condition, with no new slides or blockages. Some infiltration
water into the Tunnel was noted and measured to be approximately 38 cfm.
The sand trap at Oakdale Portal surge shaft had collected no appreciable
amount of snad and the bulkhead was removed.
San Joaquin Pipelines
Pipeline No. 1 - The mortar lining was in good condition, showing no
erosion nor deterioration on the invert section with less than 1/16 in.
depth of the lining showing signs of "dead" mortar.
Pipeline No. 2 - The lining in this pipeline shows considerable deteriora-
tion since the last inspection three years ago. Some of this changed
condition is due to the cleaning attempts performed under HH Contract 511-R.
Areas of "dead" mortar have been removed along with small pieces of lining
adjacent to cracks and previous bare metal spots. The coal tar paint
east of Oakdale is doing an adequate job of protecting the mortar lining.
Pipeline No. 3 - The mortar lining on the invert of the line has eroded
to a width of 14 in. to 18 in. ; along this trough there remains a maximum
of 1/4 in. mortar and in much of the area bare metal has been exposed.
The remaining lining shows some deterioration due to leaching cement from
the mortar by the pure water from Hetch Hetchy Reservoir. The outer 1/16 in.
to 1/8 in. is "dead" mortar and can be removed by a single pass with a
sharp metal object. Below this "dead" mortar, the remaining 3/8 in. to
1/2 in. of lining is hard, sound mortar.

TrolLey Overhead Program (TOP)
The Public Utilities Commission has filled an application with the Department
of Transportation, United States of America, for a grant under the Urban Mass
Transportation Act of 1964, as amended, for a trolley coach overhead program
for the San Francisco Municipal Railway. The program will be administered by
Hetch Hetchy Water and Power since it is responsible for power distribution
to Municipal Railway trolley coaches. The Trolley Overhead Program (TOP) will
reconstruct and replace worn-out portions of the existing trolley coach system
and construct trolley coach interconnections, turnarounds and traffic adjust-
ments .
The estimated cost of the program is $12,692,000 of which $10,153,600 (80%)
will be funded by the Federal Government and $2,538,400 (207») will be funded
from Hetch Hetchy revenues.
Installation of Depth Sensor in Rock River Shaft of Hetch Hetchy Aqueduct
A transducer type depth sensor was installed in the Rock River Shaft of the
Hetch Hetchy Aqueduct with a signal cable connecting the sensor to a digital
readout indicator in the operator's office of the adjacent Lime Treatment
Plant. This installation permits the Moccasin operator to telephone the
operator of the Lime Treatment Plant and obtain the reading of the water
level indicator. By knowing the water level at the Moccasin Reservoir and
the water level at the Rock River Shaft, the flow in the aqueduct can be
readily determined. Prior to the installation of the depth sensor, it was
necessary to dispatch a man to the Oakdale Portal of the aqueduct to read
the pressure gauge.

Sale of Diseased Trees - Baseline Road - F.ast of Camp Mather
An Agreement to sell diseased Ponderosa and Sugar Pine Trees
located on Baseline Road East of Camp Mather on property owned by
the City and County under the jurisdiction of Iletch Hetchy Water
and Power was processed through the City Purchasing Department.
Under the Agreement, twenty-seven (27) trees were sold to Mr.
tl.irk J. Wienert, Jr., of Wienert Lumber Company. A payment of
approximately $4,500, based on terms of the Agreement was trans-
mitted by Mr. Wienert to the Purchasing Department for deposit in
a Iletch lletchy Water and Power account.

ENGINEERING DIVISION - Power Improvement: Program
Work during Fiscal Year 1977-78 under the UMTA-approved Federal Grant for the
Power Improvement Program was as follows:
1 . Project Status
As of the end of the fiscal year, approximately $32 million of the $50.5
million Project grant has been expended or encumbered. The professional
services contracts for engineering design are 957- completed. Forty-seven
contracts for construction work and material purchases have been completed
and seventeen are currently in progress. Ten of the eighteen substations
have been completed and are in service, and two additional are under
construction. The old Turk-Fillmore and West Portal Substations have been
taken out of service. Electrification of the Market Street Subway and
Twin Peaks Tunnel is completed and has been tested by operation of the new
Light Rail Vehicles. Conversion of the surface streetcar overhead trolley
system for pantograph operation is nearly completed on the "K" line, the
"N" and "J" lines are under construction, and the "L" and "M" lines are in
the final design stages. Thirty-six miles of the eventual forty-five miles
of underground duct lines are completed or under construction. Approximately
557o of the 1.5 million feet of underground feeder cable has been installed
and some of the abandoned overhead feeders have been removed. Details of
the various projects and contracts are in the following sections.
2 . Electrification and Overhead Conversion
A) Contracts
Construction was completed on Contracts HH-521, Market Street Subway
Electrification, Embarcadero Station to Duboce Portal and HH-531, Market
Street Subway Electrification, Duboce Junction to Eureka Station. On
November 7, 1977, the new electrification system was energized for the
first time. Fifteen circuit breakers were closed at the recently completed
Downtown, Civic Center and Church Substations, sending 600-volt dc power
through 35 miles of power cables feeding the new 3-1/2 mile, twin-tunnel,
overhead-catenary system. All circuits tested satisfactorily. On
November 8, 1977, the first electrically powered vehicle was operated
in the new subway. P.C.C. Streetcar No. 1008, outfitted with a LRV-type
pantograph, was run from the Eureka Station to the Embarcadero Station
and back, first at slow speed and then at speeds up to 40 mph. Operation
of the pantograph on the catenary tested satisfactorily. On December 16,
1977, the first LRV was operated in the subway. 50 mph speed runs were
made by a single LRV and, on December 22, 1977, the first two-car train
made its initial runs in the subway. Testing of the two LRVs in the
subway and on the existing and partially reconstructed surface overhead
trolley system continued. Additional test runs were made, with a single
LRV and a two-car train, confirming the operation of the pantograph and
the LRV on the new catenary system and power system. Final testing of
the new catenary system in the Market Street Subway, following minor
adjustments resulting from earlier testing, was satisfactorily completed
on June 23, 1978.

Construction neared completion on Contract HH-524, K Line Streetcar
Overhead System, Conversion for Pantograph Operation.
Construction neared completion on Contract HH-536, Streetcar Overhead
System, West Portal Avenue, Conversion for Pantograph Operation.
P[P and 'HP construction work was completed on DPW Contract 23,727 for
Ocean and Phelan Avenues Rechanneli zation, which included relocation
of trolley poles and the overhead trolley wire system, along with
Muni streetcar track relocation and rerailing.
Plans and specifications for Contract HH-532, "N" Line Streetcar
Overhead System, Church Street to Nineteenth Avenue, Conversion for
Pantograph Operation, and Sunset Tunnel Electrification, were
transmitted to UMTA for approval on August 5, 1977. The plans and
specifications were approved by UMTA on August 19, 1977. Bids were
received on September 15, 1977. The contract was awarded on September
27, 1977, to Amelco Electric, San Francisco, California, who submitted
the low bid of $441,552. The contract was certified by the City
Controller on November 8, 1977. Construction commenced on November

STREETLIGHTING
General
The lighting of public streets within the City of San Francisco is provided by
facilities which are, on a City-wide basis, 44.2% owned by the City; 54.0%
owned by the Pacific Gas and Electric Company; and a small percentage, 1.8%,
jointly owned. In the underground areas, where the economic advantage of City
ownership is greatest, 82.77., of the lights are City-owned. Five years ago,
the corresponding figure was 80.27,.
In fiscal year 1933-34, the cost for street lighting was $1.25 per capita; last
H e §r , w i th approximately thirty times _a s much 1 i gh t _o n the streets and public
thoroughfares, the cost per capita was approximately $2.49.
Maintenance and repair of City-owned installations were performed under two
contracts. One provided for group replacement of lamps in accordance with
schedules developed by the Bureau. A second contract covered work required
for repair of damaged and defective equipment, painting and miscellaneous
maintenance.
Under contract, the Pacific Gas and Electric Company furnished streetlighting
service as directed, including the furnishing, maintenance and operation of
Company-owned facilities. Certain services were provided also for City-owned
facilities, including switching and control replacement of individual lamps
and globes, and emergency work required during other than normal working hours.
Electric energy for all City and Company-owned streetlight operation was
supplied by the Hetch Hetchy power system.
Engineering
The Bureau reviews, reconmends changes, approvals or rejections of, and correlates
all streetlighting installations, including that done by the Department of
Public Works, the Pacific Gas and Electric Company, the State of California,
subdividers, etc.
During the fiscal year 1977-78, 10 streetlighting contracts, involving a total
of 495 new streetlights, were approved by the Public Utilities Commission.
Plans were submitted for approval only after careful checking to determine that
illumination will exceed the minimum requirements established by the American
National Standards Institute; and that all materials used, and manner of
installation, meet with the applicable local, state and federal rules, regulations
and statues governing the installation of electrical works.
